Never seen a diesel with a catalytic converter yet, apart from the odd
bus.

I bet you see several a day but don't know.
All Astra common rail ones have a cat to start with.
I bet they are actually particulate filters.

How do particulate filter burn off the particles?
Hint, they use a catalyst and oxidise them.
So even by your definition you have seen many diesels with cats.
Mine is a two stage cat IIRC so its more than a particulate filter as it
removes un-burnt fuel and CO as well.
